How to uninstall software under Mac OS x

There are many ways to install MAC OS x software, and the software offload is very different. Removing software in Mac OS X is often not as simple as pulling the software into the trash. Typically, specific problems are analyzed. Whether you uninstall manually or with third-party software, the following issues need to be considered:

1. In what form (dmg,pkg, software installation disk, single application, or otherwise) is the software installed?
2. Does the software have an installation disk or a system that uninstalls the software?
3. Does the software help file have instructions on how to uninstall? Does the software developer's webpage provide similar instructions?
4. Have you run the software?
5. Have you exited the software? The running software can not be deleted, the application window is not the same as the exit of the app, you should use the Apple and Q key combination, or through the app's menu, or the Apple menu of the mandatory exit option to exit the software.
In the "How to install the application software" article, the installation of a file package (. pkg file) is mentioned, and a copy is generated in the repository under the hard disk or under the user's Repository receipts folder, including the installation path and permissions. When uninstalling an app installed with a. pkg package, you should first check the file that contains the installation path and permissions. The specific approach is:
1. Press and hold Apple, shift, and u, or use the Finder to navigate to the utilities (Utilities) folder under the application (applications) folder, and double-click Terminal (Terminal).
2. Under terminal input: Lsbom space
3. To the Receipts folder in the repository under the hard disk, locate the package name you want to uninstall, and hold down the CTRL key while clicking on the file. (Note: The Leopard method differs from this).
4. Select "Show Package Contents" from the menu and the Finder will open a new window with a Contents folder in it. Contents
5. Open the Contents folder, locate the Archive.bom file, pull it directly to the terminal window opened in the second step, and then enter.
6. Remove the software based on the path information.
7. Delete this pkg file in receipts.
Note: 1. Files installed in the MPKG package will produce multiple pkg files in the Receipts folder, which should be noted in each PKG when uninstalling the software, and deleted by path.
2. If a software downloads and installs the upgrade package, you may not be able to revert to the previous version of the software if you have deleted all the files in the path under Archive.bom in the latest upgrade installation package. This is because the upgrade package overwrites some of the corresponding files in the previous version, and once those files are deleted, the old version of the file does not exist. System software installed in the installation of the way to install the package, because the system software upgrades frequently, with this method to uninstall it is more troublesome, than reinstall system.
Software Installation if the software manufacturer's own installation software or installation disk, first of all to find the original installation software or installation disk, or run into the original installation software or installation disk installation interface, check whether the uninstall method. If not, exit the installation interface and check if the installation log was created prior to installation. If so, it should be deleted by the path in the installation log. Large software such as Adobe CS3 has its own uninstall software in the utility package, in addition to the installation section in the installation disk.
For software that is installed in a compressed package and in a single software way, it is necessary to pull the software from the place where it was installed, but whether it is uninstalled completely or not depends on the situation.
Third-party software Appzapper is a solution for non-system software, however, if the software being dismantled is a complex, large-scale software, or is installed with the software manufacturer's own installation software or mpkg files, it is likely that the software will not be completely dismantled with appzapper. The software should first consider whether the software has its own uninstall method.
In the case of Filp4mac wmv, you can see that appzapper can not find the installation package Filp4mac in the Receipts folder. And Filp4mac itself after the installation, in the installed folder has its own uninstall package.
For the removal of the components of the system software, the way directly to the trash is likely to cause system problems. Desinstaller is used to uninstall the software installed in the Pkg method, its greatest advantage is that the software can be removed at the same time the deleted software archive to generate an installation package to spare. Because the system software is installed in pkg mode, Desinstaller is often used to uninstall some system applications. However, when using the software to uninstall the system software, if there is a problem, it may be self-defeating, and finally have to reinstall the system.
Typically, once the software has run, it is possible to generate a property file, cache file (cached), or other satellite file. If these properties files are not removed when such software is removed, it will still be used in the future even if the software is installed. If you remove the software because the software is not working properly, and the cause of the problem is that the property files, you do not know when you remove the software, so even if you reinstall the software, the software still does not work properly. Therefore, when you remove the software, whether manually removed or use the above two third-party applications, you should go to the hard disk and the user under the Repository Preferences folder to see if there is any files or folders associated with the software that was removed. In addition to the Preferences folder, you should check the following path to see if there are any files or folders associated with the app you want to uninstall:
The Hard drive Directory
User's My Documents folder
Hard disk and user's repository folder
Caches folder under hard disk and user's resource library
Application Support folder under hard disk and user's resource library
The profile in the Colorsyn folder under the hard disk and the user's repository (especially if your app is related to the scanner)
Components folder under the hard disk and user's resource library
Contextual Menu Items folder under hard disk and user's resource library
Input Manager folder under hard disk and user's resource library
The hard drive and the user's repository under the Internet Plug-ins folder (especially when you are uninstalling the Safari plugin)
The QuickTime folder under the hard disk and user's repository (if you are uninstalling Video conversion software)
Hard disk and user's library under Screen Savers folder (if you want to uninstall a screensaver)
Hard disk and user's repository under Startupitems folder (especially if your app starts automatically when you log in)
The hard disk and the user's repository under the Widget folder (if you want to uninstall the widgets)
If you have more than one user on your machine and the app is available to all users, you should notify all users that they are also logged in to check the appropriate folders.
When these checks are done and the files are deleted, it's time to search for the software name or developer brand name to see if there are any remaining files. Some of the software has hidden files and can be searched using the command line or Smart Folder (Smart Folders), as described in the article "How to find hidden files".
In short, software uninstallation is often not a simple job, so I have "what to do before the use of new machines will be more useful for future use?" "In the article mentioned to create a folder to store the installation log, the same, when manually uninstall, it is best to also record your disassembly process in the log folder.
In addition, from the above description, it can also be seen that software installation and uninstallation of the degree of difficulty often depends on how the software developers in the development of the organization of these paths. If these paths are complicated and the developer does not provide detailed uninstallation instructions, the end user's disassembly is quite difficult. And most of the free software has this problem, so in the choice of software to install, not only to see its function, whether it is free, but also to pay attention to it has not provided a detailed method of demolition.

How to install the application software
Before installing the software, consider the location of the software installation.
The Finder makes it easy for users to find the application folder from under the hard drive and quickly understand that this folder is where most applications should be installed. Looking closely at this folder, it is easy to see that all accounts on this computer have access to and even use the app in this folder. In the Chinese display and input overview article, once mentioned that the user domain and Mac OS x system is a true multi-user system, in software applications, in fact, the advantages of this multi-user can be reflected. Specifically, users can have their own, other accounts do not see the more used applications and folders. Users can set up an application folder in their own home folder and install the application there. Even for some simple applications, it is perfectly possible to place the application on the desktop.
Some new users do not know what to do with the downloaded application, and some leave the app on the desktop, which is often ridiculed by users who have some experience with Mac OS x systems. But these old users are not clear that the multi-user system itself allows users to handle the application software. Of course, the application is placed on the desktop is not worth advocating, application software installation location should be in accordance with their own actual situation and habits of reasonable arrangements.
In addition to the system disk with the application software (specific installation method, see the Random User manual), Apple Software installation method basically has the following: Apply disk image (. dmg file), package (. mpkg or. pkg file), compress files (. Sit,. zip,. rar, etc.), Software developers make or commercial third-party installers or scripts (script), as well as single apps.
In these ways, the way in which packages are normally applied is determined, and the way that software developers make or commercially use third-party installers or scripts in some cases is deterministic, while others allow the user to choose the appropriate folder for installation. The two approaches are almost automatic, and the software installs automatically as soon as the user clicks on the installer. Of course, in some cases, users will be asked to agree to the software's use policy, or enter the administrator password. If not specifically stated, the installation is also for desktop applications (so-called desktop applications), after installation, you should go to the application folder under the hard disk to find.
Package installation requires the "installer" (Installer) in the calling Utilities folder. If you do not have this "installer" software under the Utilities folder in your machine, you will not be opened. mpkg and. pkg files. After the package is installed, a copy of the. pkg file is stored in the Repository Receipts folder or under the user's Receipts folder under the hard disk. The pkg file stores a Archive.bom file that records the path and permissions of the software installation. In addition, the way the package can be installed remotely with Apple Remote Desktop is very convenient. After installing using a software developer's own or commercial third-party installer or script, the installation log is typically generated, and the logs generated by different software vary.
. mpkg file icon
The icon for the image file (. dmg) on the desktop is the hard disk shape. If it is downloaded and installed, the image is automatically loaded (mount) after it has been verified for completion. At this point, a white sleeve-like icon (volume/volume) appears on the desktop, and a new Finder window opens, displaying the contents of the file. If you accidentally close the Finder window and pull the white sleeve icon into the Trash, you can double-click the DMG hard drive icon to make the white sleeve appear on the desktop again. Double-click the white sleeve and the Finder will display the app content. Usually, you can move the contents of the Finder directly to the place where you want to install the software, and then you can pull the DMG hard drive icon to the trash and clear it. Some software developers have an icon in the DMG file that indicates where to move the file (e.g., application folder). Some developers are more fine, in addition to the icon, but also add the installation position of the alias, as long as the application to the alias icon, the installation is complete.
The image file, in addition to installing the app, can itself be a disk image, which is installed or repaired by the disk Utility recovery (restore) feature.
DMG files, white socket-like volumes, and volume content opened with finder
MAC OS x System itself has a certain decompression function, so like. zip files, double-click the same as with the normal folder with the Finder window open, as long as the contents of the inside to move to the place where you want to install the application, even if the installation is successful. Of course, if the compressed file itself is an installer, you will also need to double-click the installer to install the program. Some compressed files cannot be extracted using the decompression method that comes with the Mac OS X system, and these files can be processed with StuffIt Expander or other StuffIt software. This is why the software is listed as a prerequisite software.
For a single app, move directly to the application folder under your hard drive, your own set of folders, or the folder you specify.
After the software is installed, if it is convenient to use, you can go to the folder of the installed software, pull the software icon directly to the dock (the dividing line to the left or the top), so to use, click on the dock label, set the corresponding file directly to the app icon on the dock to run the app.
